The amount of energy used in the lifetime of a building depends largely on construction methods and materials. The property sector accounts for around 18 percent of greenhouse gas emissions in Sweden, and there is significant room for innovation in the building sector.

Interest in solar cells is growing rapidly

Do you have a battery-free pocket calculator? Then you probably own a solar cell – a piece of equipment which converts sunlight into electricity. Solar cells have been around for a while, but they are still relatively expensive even though the raw material, sunlight, is free and unlimited in many places around the world. The sun provides our planet...

Fibre optics bring light to dark rooms

Fibre optics can create a more wholesome indoor environment and save energy. For practical reasons, work in the traditional farming community followed the availability of daylight. Most of us would still probably prefer to work in natural rather than artificial light. Studies confirm this instinct, and the fact that health and productivity increase in premises with access to natural...

Efficient light sources and light management save energy

Lighting is responsible for between 30 and 45 percent of the total energy consumption in an office block. A modern lighting installation can, however, halve the energy consumption. This requires a combination of energy-efficient light sources and reflectors, as well as a system for managing the light. A side effect is that energy-efficient light fittings also produces less heat,...

Low-energy light bulbs without mercury

With the aim of developing a low-energy light bulb which works without mercury, Russian scientists and scientists from Chalmers University of Technology in Sweden have worked together to develop a field emission cathode, a cold cathode which produces a flow of electrons. The benefit over traditional hot cathodes is the reduction in heat loss. Hot cathodes can be found...

Heating systems to safeguard the future

The old oil-fired and electrical boilers used for heating homes really are past their sell-by dates – both from an environmental point of view and in light of the rising fuel prices. Some households have gone over to heating systems based on renewable energy, or have linked up to district heating networks. What may a smart future heating system...

Passive houses

The idea behind a ”passive house” is that it does not require a traditional heating system run, for example, on oil, wood or electricity. Instead, the energy should come from other heat sources, such as fridges, cookers and computers, and by utilising solar radiation. These heat sources may be supplemented by other measures which minimise the heat loss from...

Houses for the future

Energy- and resource-efficiency are important ingredients when buildings are planned, designed and built. There is no real conflict between attractive architecture, a sound indoor environment, energy-efficiency and reduced environmental impact, but architects and engineers must choose environmentally-adapted options. If a house is to be built with the environment as a central consideration, environmental sustainability must be part of the...
